Lochinvar & A.O. Smith 100327058 Motor Assembly

The Lochinvar & A.O. Smith 100327058 Motor Assembly is the direct performance replacement for legacy part numbers 100166707 and PVT1014. As a critical induced draft motor, this assembly is engineered to maintain precise negative pressure within the heat exchanger, ensuring the safe exhaustion of combustion byproducts. For technicians servicing high-efficiency commercial water heaters or boilers, this OEM inducer motor assembly provides the exact mounting footprint and electrical specifications required for a seamless "drop-in" installation. The 100327058 motor features a robust housing and a balanced impeller to minimize vibration and prevent common pressure switch faults often seen in failing units. By pulling air through the burner and venting flue gases, this direct replacement inducer restores factory-spec combustion cycles and prevents system lockouts caused by seized bearings or open windings. When your diagnostic confirms an HVAC draft inducer failure, using this genuine 100327058 assembly ensures long-term operational stability and maintains the original equipment’s efficiency ratings.

• Direct OEM Interchange: Replaces obsolete parts 100166707 and PVT1014 without the need for field modifications or bracket fabrication.
• Optimized Combustion: Engineered to provide the specific RPM and CFM necessary to satisfy system pressure switch requirements and ensure clean ignition.
• Quiet Operation: Precision-balanced blower wheels reduce mechanical noise and harmonic resonance during the heating sequence.
• Simplified Service: Complete motor assembly includes the housing and necessary components to reduce technical downtime and labor costs.

How do I confirm if the 100327058 is the right replacement for my 100166707?
This inducer motor is the manufacturer-designated upgrade. Check the data plate on your existing assembly; if it matches 100166707 or the PVT1014 series, this draft motor replacement is the correct spec for your unit.

What are the signs that my current inducer assembly is failing?
Technicians should look for pressure switch errors on the control board, high-pitched bearing whine, or a motor that is "hot to the touch" but fails to spin. If you detect a burnt electrical smell or the impeller is seized, a full assembly replacement is required.

Does this assembly include the gasket?
Most OEM assemblies are shipped with the mounting gasket to ensure a gas-tight seal at the flue collector. We recommend verifying the seal integrity during installation to prevent CO leaks or condensate bypass.
